A Brief History of Disney Blu-Ray: 1.) Disney lobbies hard for the industry to choose Blu over HD.
1) Toshiba was in Microsoft's pocket for pushing HD, since HD becoming the format would give Microsoft the coding monopoly on all hi-def and streaming titles. Steve Jobs, on the board for Disney, lobbies hard for Blu and keeps Disney the most faithful Blu fortress, which would keep an Apple-friendly MP4-derived video coding, and more accessibility for everyone, if and when Apple included Blu drives.
2.) After a hard-won victory in the "format wars," Disney pretty much ignores the Blu format for about three years and just keeps on releasing its catalog titles as dvd only.
2) But then, that victory WAS hard-won, and nobody wanted to make a move until it was. FWIW, Disney's credited with lobbying harder for mainstream/family Blu acceptance than Sony itself was, while had been publicly embarrassing itself--and
giving HD an advantage with film buffs--by giving the format a negative action-adrenaline teen stereotype to keep their PS3 audience. And IIRC, Disney was already out of the gate first with their high-resolution CGI movies (Dinosaur, Chicken Little), since back then, nobody knew whether traditional non-CGI animated would "work" on Blu either, and stayed away from it.
3.) Disney finally starts unloading its fabulous vaults of Elder Product; "restores" animated features to such a high degree that they end up looking like made-for-tv cartoons from the 1990s.
3) Although keep in mind, one of the reasons we got Sleeping Beauty fresh out of the gate was in 2008, studios literally
didn't know whether audiences would accept anything but 16:9 movies whatsoever on widescreen sets. There was a lot of very strategic hemming, hawing, and dragging of feet from studios, and if Disney hadn't been "forced" to come to terms with releasing Snow White, and creating the Disney/View borders to sell it, 4:3 Classic Blu movies might have been permanently down the river at all the studios. (Some were even debating the "marketability" of Cropping.)
4.) Experiments with "combo packs" and other differing packaging formats--all in a grand attempt to confuse consumers and drive people away from Blu--the format that it lobbied so hard for the industry to accept (see #1).
4) THEY tried to make it easy, WE confused it.
(The first '08 ads, and even the first '10 3D ads, said "Buy ahead!", but even the most current DVD/Combo ads say "An extra for your laptop!" Thanks loads, guys--Just remember who gets the blame.)
